Answer:
0.249
Step-by-step explanation:
tan(theta) = opposite / adjacent (according to the SOH CAH TOA rule), which effectively means y/x in this case.
So -0.242 / -.970 ≈ 0.249
Other explanation:
On a unit circle,
y = sin(θ)
and
x = cos(θ).
And since, tan = sin/cos, tan(θ) = y/x. You y and x are given, so calculating tan is a matter of dividing them.
The answer is a=-3. just add the -2 and the 3 so that would be a+1=-2 then subtract the 1 from both sides to get the a alone.
Answer:
There is 166.1 grams of sugar in 5.5 yards of licoroce
Step-by-step explanation:
If 1.5 yards of licorice = 45.3 grams of sugar
5.5 yards of licorice = x
Cross multiply:
45.3grams * 5.5yards / 1.5yards
= 249.15 grams/yards / 1.5yards
= 166.1 grams of sugar
L is length
w is width
p is perimeter
l = 3w-2
When a problem says "less than" (not "is less than"), you should put the minus sign BEFORE the number.
p = 60
The formula of perimeter is 2l + 2w
60 = 2l + 2w
Replace the l with the formula of l.
60 = 2(3w-2)+2w
Solve the problem:
Distribute
60 = 6w-4+2w
Combine lile terms
60 = 8w-4
64=8w
Divide
w=8
The interquartile range is 7
so a
